Introduction:

CASTECH offers a wide range of prism types in a variety of designs, substrates, or coatings such as Penta Prisms, Right Angle Prisms, Dove Prisms, Roof Prisms, Porro Prisms, Retro-Reflectors, Anamorphic Prism Pairs, Pellin Broca Prisms, Equilateral Dispersive Prisms and so on. We employ different processing methods such as conventional polishing, continuous polishing, or ion beam figure(IBF) as well as top metrology equipment, tailored to deliver high precision optical prisms for the most demanding requirements in high power laser, scientific and industrial applications. 

Features:

  • Material from DUV to IR  
  • Custom dimensions and shapes  
  • A wide range of optical prism types  
  • Standard and custom coating options available  
  • High laser damage threshold

Specifications:

 

Material BK7  or  UV fused silica
Dimension Tolerance +0/-0.25mm
Clear Aperture >central 85% of dimension
Beam Deviation <3′
Surface Quality 40/20
Flatness

λ/4 @632.8nm

Chamfers

0.25-0.5mm face width (typical) ×45°±15°

 

Right Angle Prisms:

•  Total internal reflection prisms.  

•  90°or 180° beam deflection, depending on which surface is used as the input for the light source.

 

Right Angle Bending Prisms,Uncoated:

•  90°  reflectors

RAPB-254-UVFS 25.4 UVFS

 

 •   Our Right Angle Bending Prisms are also available with antireflection coatings on both legs in order to reduce surfaces loss;

  •   Coating specifications upon request;                              

  •   Other sizes and coatings are available upon request.       

 

  Example : The hypotenuse may be coated with second-surface aluminum protected by black sealing paint to ensure total reflection of incident light.These prisms are suitable for optical delay lines and for high power use.
